Asphalt shingles are the most common residential roofing materialatop Charlotte NC and Rock Hill SC roofs. Asphalt shingles are used on so many residential roofing projects for very good reasons:They perform well in extreme temperatures, require low maintenance, and are fire and wind resistant. Asphalt shingles come in more than a dozen different colors, both solid and blended, and are guaranteed for 20 to 30 years, making asphalt shingles an excellent value for residential roofing.
Asphalt roofing ABCs
Asphalt roofing is made of asphalt soaked felt paper or fiberglass matting, coated with another layer of asphalt and then covered with mineral granules to extend the life of the shingle. The lighter the color of the granules, the more light and heat is reflected. Asphalt roofinghistorically has been classified by weight; 100 square feet of asphalt shingles of a certain thickness and weight, called a square, isratedwith an average life expectancy of 12 to 15 years. Heavier shingles can be expected to last longer. Weight per square changed to classification by expected wear when manufacturers began using the lighter fiberglass matting in their shingles rather than felt paper. Today, asphalt shingles are classified by the warranty offered by the manufacturer, andcommonly referred to as 10 year, 15 year, 20 year, 25 year, 30 year or 35 year shingles.
Advances in asphalt shingles
With advances in manufacturing techniques, asphalt shingles are available in various colors, textures and edge patterns. Since the mid-1960smost asphalt shingles are self-sealing, in which a strip of tar edging on one shingle fuses with an overlaying shingle in the heat of the sun. This sealing process helps prevent single shingles from being blown off in a wind storm. Older, non-sealing asphalt shingles often succumb tostrong winds and end up on the ground.
Wear on Asphalt Shingles
Regardless of the type of asphalt shingle is used, they do wear out over time. Sunlight does a great deal of damage to asphalt roofs, and consequently south and west exposures tend to wear out the first. The lighter the shingle color, and the steeper the roof pitch, the longer the shingles will last.As asphalt shingles wear, they gradually lose their granular shield,and ultra-violet light causes them todry out and become brittle, crack, buckle, and curl. An area where granular material has eroded tends to wear from heavy foot traffic, tree branch abrasion, or water erosion from downspouts onto the roof surface.
Residential roofing maintenance
Asphalt shingles require regular inspection and maintenance to confirm your roof performance is still at its peak. Unless you are a trained roofer,Advanced Roofing and Exteriors recommend you stay on the ground and hire residential roofing experts to inspect your roof for damage and for potential problems with your asphalt roofing. Water damage is an ever present risk, and your residential roofing expert will check to see that your roof is free from water-retaining debris and that drains are clear, especially around pipes and pitch pans, and behind HVAC units. If your asphalt roofing is starting to collect moss or algae, suffer abrasion from tree branches, loose granules, lift or curl, your professional residential roofing contractor can make the necessary repairs and save you costly trouble later on.
